Why I find this part of the scene exciting and dramatic is because the friction is very high and you can feel the blood boiling on either side of the family. This then leads on to further conflict and death.
Tybalt then sees Romeo and immediately starts insulting him within seconds of seeing him “Romeo, the hate I bear thee can afford No better term than this, thou art a villain.”
This then makes the others angry but Romeo stays relaxed and tries to calm Tybalt down by saying “Tybalt, To such a greeting: villain am I none; Therefore farewell; I see thou know'st me not.”
But Tybalt refuses to calm down and listen to Romeo’s explanation and replies “Boy, this shall not excuse the injuries that thou hast done me; therefore turn and draw.” Romeo claims to have done nothing “I do protest, I never injured thee, But love thee better than thou canst devise, Till thou shalt know the reason of my love:
And so, good Capulet,--which name I tender As dearly as my own, be satisfied.”which means This then makes us feel that a fight is brewing in the depths.
Them Mercutio steps in to the conversation in defence of Romeo and says “O calm, dishonourable, vile submission! Alla stoccata carries it away,” as he draws his sword. “Tybalt, you rat-catcher, will you walk?”: this is the start of the fight when Mercutio steps in to be loyal to his brother but Tybalt complains and says “What wouldst thou have with me?” Mercutio explains and states that he has lived his life to the full and has enjoyed it and is willing to die now for his brother. So Tybalt draws his sword in honour of his family and says “I am for you!”
Mercutio then torments Tybalt and says “come, sir, your passado” But then Romeo steps in and tries to stop the fight by saying “Draw, Benvolio; beat down their weapons. Gentlemen, for shame, forbear this outrage! Tybalt, Mercutio, the prince expressly hath forbidden bandying in Verona streets: Hold, Tybalt! Good Mercutio!
But Tybalt couldn’t care less he, carries on, and under Romeo’s arm stabs Mercutio and flees.
Mercutio says I am hurt. A plague o' both your houses! I am sped. Is he gone, and hath nothing? Benvolio asks if he is hurt and says “What, art thou hurt?” but Mercutio replys“Ay, ay, a scratch, a scratch; marry, 'tis enough. Where is my page? Go, villain, fetch a surgeon.” This makes it highly dramatic as now it’s a matter of life and death not like past play fight.
After that drama it leads on to another where Romeo says “Alive, in triumph! And Mercutio slain!
Either thou, or I, or both, must go with him.” which Tybalt does not take very well and replies “Thou, wretched boy, that didst consort him here, Shalt with him hence” so in conclusion of this they fight.
Then tybalt falls and before anyone can see Benvolio tells Romeo to “…be gone!” and upon hearing this he flees!
This causes more upset for both families, as each family has had a family member die! But under the skin this turns in to more anger against one another.
Moreover, at the very end the princes speech adds excitement and drama to the reader by making us wait to find out what will happen to Romeo and the two families after the conflict known by the whole town and then we find out Romeo is banished and the two families are fined.
So in conclusion why I think act 3 scene 1 is the most interesting, exciting and dramatic scene in the play is because it is packed full of fights and drama throughout the scene starting with when the two families meet and ending when Romeo is banished and there are two less characters in the play!
